L. I By A iiomeys Patented Jan. 28, 1941 UNITED STATES PATENT QFFECE 1Claims.

The present invention relates to receptacles for milk bottles and hasfor its primary object to provide a device of this character withinwhich the bottle of milk is adapted to be deposited and 5 embodyingsignalling means to indicate when an empty bottle is removed from theholder and another bottle placed in position therein.

A further object of the invention is to provide a milk bottle holder ofthis character embodying a pair of electrical contacts arranged incontacting engagement for energizing the circuit when the holder isempty, one of the contacts being movable and adapted to open the circuitwhen a milk bottle is placed in position in the holder.

Another object is to provide a device of this character of simple andpractical construction, which is efiicient and reliable in performance,relatively inexpensive tomanufacture and install in operative positionand otherwise well adapted for the purposes for which the same isintended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawing forming part hereof, wherein likenumerals refer to like parts throughout, and in which Figure 1 is aperspective view.

Figure 2 is a side elevational View.

Figure 3 is a vertical sectional view.

Figure 4 is a similar View taken substantially on a line 4-4 of Figure2, and

Figure 5 is a top plan view.

Referring now to the drawing in detail, the numeral 5 designates a milkbottle holder of insulation material and which preferably is ofsubstantially box-like construction open at its top and including a backwall 6 adapted for attaching to a suitable supporting structure and alsoincluding a bottom I.

Secured to the bottom I, at the inside of the holder, is a stationarycontact plate 8 and secured at its upper end to the inside of the backwall 6 is a spring contact plate 9 having its free end l yieldably heldin: contacting position with an adjacent edge portion of the contact 8by the spring tension of the plate 9. The contact plate 9 is securedflatwise against the inner surface of the back wall 6 of the holder withits lower free end urged away from the wall toward the center of thebox, as shown by the full lines in Figure 3 of the drawing.

A terminal ll extends through the bottom I for engagement with thestationary contact 8 and to which a circuit wire I2 is attachedextending to a suitable source of current l3. A terminal [4 also extendsthrough the back wall 6 for engagement with the secured upper end of themovable contact 9, said terminal likewise having the circuit wire l5connected thereto which also leads to the source of current l3 and hasinterposed therein the switch It and the signal I1, which in the presentinstance is illustrated as comprising a buzzer or other audible signal.

It will be apparent from the foregoing that when a milk bottle, such asindicated at I8, is positioned in the holder, the contact 9 will moveout of contacting engagement with the contact 8 whereby the circuit willbe broken.

When placing the device in use an empty milk bottle is placed in theholder, thereby separating the contact, and the switch I5 is thenclosed. When the empty milk bottle is removed from the holder, as by adeliveryman, the contact 9 will serve to close the circuit therebysounding the alarm, and when the full bottle is placed in the holder thecircuit will again be open, the device thus providing for a temporaryclosing of the circuit sufficient to indicate that the bottle of milkhas been delivered to the holder.

It is believed the details of construction and manner of use of thedevice will be readily under- 0 stood from the foregoing without furtherdetailed explanation.

Having thus described the invention, what I claim is- An electric switchfor a box-like bottle holder in which the holder is open at its top,said switch comprising a stationary contact covering a portion of thebottom of the holder and a movable contact engageable therewith and saidmovable contact embodying a bottle actuated spring plate securedflatwise in a vertical position to an inner side wall of the holderadjacent the upper portion of the wall, said plate being inclinedinwardly to gradually reduce the area of the box toward its bottom, thelower end of the plate being free for moving into and out of engagementwith the stationary contact, said movable contact being in the path ofthe bottle for wiping engagement therewith during its inserting andwithdrawing movement to make and break connection with the stationarycontact.
